The robust ladder-type frame is not easily upset. Its closed profile makes it particularly stable and torsion-resistant – an advantage compared to ladder-type frames with a U-profile. The rigid axle on the rear wheels also carries heavy loads and, with its larger axial crossover, improves the traction offroad. But the X-Class is not happy with robustness and loading capacity alone. Thanks to the multi-link rear wheel mounting with coil springs there is no shortage of driving fun or driving comfort.
